Application June 8, 1936, Serial No. 84,149 26 Claims. (01. 164-411) This invention relates to a machine for punch ing perforations in cards, such as address bear ing stencils and printing plates, employed in ad the perforating of such selected zone. Another object of the invention is a card per forating machine comprising an index plate hav ing zones corresponding in position and number 01 to the perforation receiving zones of the card, punching mechanism including a pointer mov able into register with a selected zone of the plate for positioning a punch in register with the cor responding zone of the card,‘ and means con dressing machines in the manner described in ;.5 the copending applications of Harmon P. Elliott, Serial No. 69,803, ?led March 20, 1936, and Serial No. ‘75,118, ?led April 18, 1936. Such addressing machines are arranged to re cord on a record sheet, usually concurrently with 10 the recording of an address, selected items of trolled by the pointer for effecting a punching operation of the mechanism. A yet further object of the invention is the statistical information denoted by the relative position of marks formed on the record sheet un der control of perforations located in selected differently positioned zones of the address bear ~15 ing. stencil or printing device. The stencil or provision of a card perforating machine having _ a perforating device and indexing means con 15 trolling both the position of the perforating de vice with respect to>the card to be perforated, printing device is provided with a plurality of differently positioned zones, each zone represent and“ the operation of' said device. Another object isv generally to improve the construction and operation of card Perforating ing a different item of statistical information and adapted to have a perforation when such item 20 is to be indicated on the record sheet. vOne of the objects of the present invention is an improved machine for selectively perforating‘ the cards, as the stencils or other printing de vices, for this purpose. In a copending concurrently ?led application 25 of’Harmon P. Elliott, Serial No.’ 84,150, a card perforating machine is disclosed utilizing a plu rality of punches selectively caused to be oper ated at the will of the operative to form the per forations in desired zones of the card. It is an object of the present invention to provide a - card perforating machine wherein but one punch * . corresponding zone of the card whereby to effect 1 machines. ‘ . Fig. 1 is a front elevation of the perforating machine embodying the present invention. ‘ Fig. 2 is a cross sectional detail of the machine taken along line 2-—2 ‘of Fig. 1. ' v dex plate and the punch positioning mechanism. Fig. 4 is a sectional detail of the operating mechanism for the punch ‘reciprocating member taken along line 4-4-4 of Fig. 2. Fig. 5 is a sectional elevation of the perfora is employed, the punch being movable into reg tion selecting pointer. ister with zones of the card selected at will by the pantograph linkage connecting the pointer 35 the operative and caused to be operated to form a perforation in the card when located in any selected position. A further object of the invention is the pro vision of a reciprocating punch operating plate 4O that confronts the perforating receiving zone of the stencil and has an area approximately coex tensive with the area of such zone and a punch interposed between said plate and the card or stencil and capable of being located in any se 45 lected zone of the card and operated by the plate. Another object of the invention is the provision of a card perforating machine having a single 50 movable punch and an index plate divided into zones corresponding in number and position to the perforation receiving zones of the stencil, and means so arranged that when a pointer is ' Fig. 6 is a detail of the supporting bearing for and punch, taken along line 6—5 of Fig. 3. As illustrated in Fig. 3, the card or printing de vice comprises a stencil l6 having in one portion a stencil sheet l8 bearing an address 20, and in another portion a series of zones 22, the different positions of which denote different statistical items. . The zones 22 are arranged in horizontal and vertical columns and are consecutively num bered as at 24. ‘ The stencil herein shown has provision for one hundred and ?ve (105) zones although the pre cise number is of no particular importance to the present invention. Each zone is preferably pro vided with a mark as a small circle 26 printed thereon for indicating the location of a possible 50 perforation. When the stencil is perforated by the machine of the present invention such marks 26 are not necessary. They are desirable, how ever, for indicating the location of a perforation 55 the punch will be disposed in register with the ' that may be formed subsequently by hand. positioned at a selected zone of the index plate 25 Fig. 3 is a plan view of the middle portion 0 the machine and illustrating particularly the in- 2 2,127,681 The stencil is adapted toreceive perforations 28 in selected zones. The perforations control the passage of marking members through the stencil and into pressure applying relation with III a record sheet thereunder for the purpose of ‘lower end of the rod is connected to an eccentric strap 58 operating on an eccentric ll’ll) journalled loosely on a shaft 502. Said shaft is rotatably supported in bearings Hi4, see especially Fig. 1, and is continuously rotated from the continu making a mark on the record sheet in a location corresponding to the location of a perforation, ously rotating shaft 36 of the’ power mechanism by means of pulleys W8, W8, and the belt H0. The marks thereby indicate by their position on the record sheet the items of information de noted by the perforated zones of the stencil. The machine for perforating the stencil com prises a table 30, see Figs. 1, 2 and 3, supported on uprights 32 and having its operative parts The eccentric 805 is adapted to be connected with the shaft N32 for rotation therewith by operated by a power device 34, now common in the art. The power device includes a continu4 ously rotating shaft 36 and an intermittently rotating shaft 38, the latter shaft being arranged to make one complete revolution per operation and then to stop. The rotation is under control 20 of a pedal 40, which when depressed and subse quently released effects one complete rotation of the shaft 38. A collection of the stencils l6. preferably with the addresses 20 thereon is contained in a holder ‘i2 disposed at one end of the table 3!) and in reg ister with the entranceof .a stencil track formed by a pair of horizontally spaced guide rails M which are spaced above the table. The succes sive lowermost stencils of the holder are advanced 30 in successive order into and along the track by a reciprocating pusher 46. Said .pusher is recip rocated by a vertical lever>48 pivoted to the frame of the machineat 50 and connected to the pusher by a link 52. The lever is reciprocated by means 35 including an eccentric 54 which is ?xed to and is rotatable with the shaft '38. The eccentric has an eccentricstrap 58 that is swiveled to the end of a pivoted arm 58 that reciprocates a leverr?? bearing against the lever 48 and connected there 40 to through a tension spring 62. The arrange ment of the arm 58, lever 60' and spring 62 issuch as to. permit reciprocation of the parts as a unit under ordinary conditions but'to permit the lever to stop reciprocation if astencil or printing de 45 vice should jam in the track‘ M. The perforated stencils are discharged from the end of the track into a stencil receiver 64. ' The successive stencils rest momentarily sta-. tionary in the middle portion of the track where they are operated upon by the punching or per forating mechanism. Said mechanism includes a bracket 66 ?xedto and upstanding above the table 30 alongside and in the rear of thestencil track. Said bracket is provided with a-pair of 55 parallel bosses 68 in which apairof vertical rods ‘H! are reciprocable. A punch operating member 12 is ?xed to the upper ends of the rods 10- by means including nuts 74 .and reciprocates with the rods. Said member 12 is in the form of a 60 ?at plate which is positioned above and overlies substantially completely the entire perforation receiving zones of thestencil. . The lower ends of therods below the table are connected by a plate 18. The rods are recipro 65 cated by toggle mechanism which includes a bracket 88 ?xedto said plate 18 between the rods. A pair of toggle links 82 are pivoted at 84 to. said bracket .and have their upper ends disposed .be tween and pivotally connected at 86 with the short arm .88 of a bell-crank lever. Said bell crank lever is pivoted on a shaft 90 carried by a bracket 92 ?xed to’ the underside of the table 3!]. The long arm 94 of said bell crank lever. ex tends rearwar'dly of the machineiand is pivotally 75 connected to the upper end of a rod 96. The means of a ratchet Hi2 ?xed to the shaft on one 10 side of said eccentric. A collar H4 ?xed to said shaft on the other side of said eccentric serves to hold said eccentric from axial displacement. Said ratchet l i2 is provided with a series of teeth i it, four teeth being here shown. Said teeth are 15 adapted to engage a pawl H8 ?xed to a shaft E28 pivoted in and extended through the eccen tric. Said shaft has an arm I22 ?xed thereto on the other side of the eccentric which is engaged by a tension spring H24 that continually biases 20 said pawl for‘movement towards the ratchet. ‘When the pawl is engaged with a tooth of the ratchet the. ratchet and eccentric are rotated conjointly. When, however, the pawl is disen gaged from a ratchet tooth the eccentric remains 25 stationary with the eccentric-at the top ‘of. its stroke. The reciprocation of theeccentr'ic serves to straighten andcollapse the operating toggle consisting of the links 32 and the short bell crank arm 8% and thereby reciprocates the punch oper v30 atingplate lfitoward and away, from the stencils. The engagement of the pawl vI N3 ‘with and its disengagement from the ratchet HZis e?ected by means of an electromagnet 126. carried'by the plate l3 and having an ‘armature or core 35 i253 movable into-and out of the magnet. Said core is connected to and reciprocates a slide bar I39 which slides in a bracket I32 ?xed-in the under side of saidplate, l8 andrhasits rear end disposed in the path of rotation of the latch 40 i it. A tension spring 1344 is connected with said slide bar we and serves normally to maintain the slide bar and the armature in a retracted posi tion. In this position therear end of ‘the slide bar can be engaged by the latch 0 it ‘as it rotates. 45 The operation is such, that the. rotation of ‘the eccentric Idisc see with the latch in engagement with the slide bar, and also the upward movement of the bar, causes the withdrawal of the latch from engagement with a ratchet tooth,_thereby freeing the eccentric‘ from the vcontinuously ro tating shaft Hi2 and holding'the’eccentric and the mechanism associated therewith from further movement. When, however, the electromagnet 50 £26 is energized thejarmature or core ‘I23 'is moved to‘ retracted position ‘and the end of the slide bar ‘H39 is pulled out from‘ under the nose of the latch H8. The latch springil'2llfthen be comes operative to swing the latch into-engage ment with the ratchet to cause ~the latch to ‘be engaged by a ratchet tooth and vcarried around therewith. The electromagnet is intended to' be but momentarily energized so‘ that the slide’ bar 6,0 is positioned in‘ the path of rotation of they latch before the'latch has made a complete revolution. 65 Hence the slide bar 'is in position to be‘engaged by the latch and to cam it out of engagement with the ratchet upon the completion of a single revolution, thereby ‘to stop further reciprocation of the mechanism. The bar‘ also holds the mechanism stationary with the eccentric‘at‘the top of its stroke. ’ ' 'In accordance‘ with this invention a single punch device H4 is employed. Said punch de vice is carried by a system of copying linkages 3 2,127,681 and particularly a pantograph system of pivotally connected links comprising the long punch car rying link I76, and the shorter link H8. Said links are maintained in parallel relation by a pair of long and short cross links I80 and I82, respec tively, which are pivoted to the links [l6 and I78. The inner end of the link I18 is secured to a ?ange M30 located in a recess of the table 36 formed on the upper end of a relatively long stud shaft I85 journalled in a bearing block E88 secured to the underside of the table, see espe cially Fig. 6. This arrangement provides a steady pivotal support for the pantograph. The free end of the lever I80 is terminated in a pointer The 15 I00 hereinafter to be more fully described. pointer, punch and axis of the pantograph link age are in the same line and consequently the punch is caused to faithfully follow the movements of the pointer. The rear part of the punch carrying arm I'IB is bifurcated, the furcations I'I?a and I'ltb being on opposite sides of the stencil track All. The furcation I'l?b at its rear end where it underlies the stencils in the track has a generally cylindrical punch passage H2. The upper furcation i'?o. The pointer I90, see especially Fig. 5, comprises a bushing 2I0 secured in and upstanding above the free endof the link I80. A plunger 2I2 is reciprocable within said bushing and has a con ical or tapered lower end 2M adapted to be de- i pressed into seating engagement with any recess 208 of the index plate. Said plunger has an en larged head or flange 2I6 at its upper end ‘which is located movably within a cap 2I8. A heavy helical spring 220 is located within the cap be tween the upper end thereof and the head 2H5 and a lighter helical spring 222 is located under said head 2 I6 and on the end of the bushing 2 I0. The cap is provided'with a vertically elongated slot 224 within which a screw 226, screw—threaded into the bushing, is located whereby to limit the vertical displacement of the cap. The spring L15 222 normally holds the plunger 2I2 and the vend cap in the uppermost positions thereof with the bottom wall of the slot 224 against the limit 1.2.0 screw 226. By pressing the cap 2 I8 downwardly i the light spring 222 yields causing the end of the plunger 2 M to enter and seat in a depression 208 of the index plate in register with the plunger. The cap 2IB carries an axially located circuit 12.5 controlling contact pin 228 which is axially mov carries at its rear end the major part of the able within the plunger 2I2 and normally is held punch device I'M. The punch device I14 com prises a barrel I94 which is fixed in and upstands by the spring 220 with its lower end withdrawn above the rear end of said furcation H60; and within the lower end of the plunger. When, how~ ever,'the lower end of the plunger is seated in a 30 ‘carries a cylindrical punch rod I?? the lower recess 203 further depression of the cap 2H3 end of which is capable of being projected below causes the flexing of the spring 220 and thereby the furcation Ilsa and through a stencil there permits the movement of the pin downwardly under and into the passage I02 of the under lying furcation 5102). The punch rod 6% is beyond the end of the plunger and into the bot~ 35 urged continually upwardly by a helical spring I08 that encircles the rod within the barrel and bears against a shoulder 200 of the rod. The rod projects upwardly above the top of the bar rel in a position to be engaged by the recipro cating plate ‘I2 and moved downwardly through the stencil. tom of the recess 288 and into- engagement with , the metallic contact plate 230 which underlies the index plate and is accessible through all of the recesses 200 therein. Said plate 230 is suit ably insulated from the frame of the machine as by the shelf 232, which is of insulating material. 40 Said plate 230 is connected in series with the ' It will be apparent that by moving the pointer terminal of the solenoid I26 and a suitable power I00 of the pantograph linkage the punch will source 230a by a conductor 230?). The other terminal of the solenoid is grounded to the ma be correspondingly moved and thus can be posi chine frame by a conductor 2300. Thus the en— 45 tioned into register with any selected perfora 45 -' ergizing circuit for the solenoid is completed by tion receiving zone 22 of the stencil to form a engagement of the pin 228 with said plate 2230, perforation therein. The pointer I00 is movable over an index plate thereby to effect a punching operation, said pin being mechanically and electrically connected to 202 carried by a shelf 232 of the table 30. Said the machine frame through the links I80 and H8. 50 index plate is divided into perforation indicating The operation of the machine is simple.v The zones 204, there being as many such zones as there are corresponding'zones 22 of the stencil operative momentarily depresses the pedal 40 to and the relative disposition of such zones corre sponding to the zones of the stencil. The index 55 plate zones are consecutively numbered as at 206, corresponding to the numbering 24 of the zones of the stencil except that the numbers are oppositely arranged. That is to say, while num ber one zone, for instance, of the stencil, occué 60 pies the uppermost left hand corner thereof. number one zone of the index plate, occupies the right hand corner. By positioning the pointer I90 of the pantograph system in register with any selected zone of the index plate, the punch 65 I'M will be caused to be positioned in register with the corresponding zone of the stencil. Each zone 204 of the index plate isprovided ' with a recess 208 preferably of conical or tapered configuration for accurately locating the pointer 70 in engagement with the plate in a position cor“ responding to the perforation position in the cor responding pointer and zone consequently of the stencil the punch anddevice holding against , accidental displacement during the punching op eration. 1 effect the movement of a stencil into perforating position under the plate ‘I2 and pointer I00 is then moved into position above a selected recess 55 208 of the index plate and the plunger 2I2 is positioned therein. The punch is thereby posi tioned in register with the corresponding perfo ration receiving zone of the stencil and at the same time is held against accidental sidewise dis— 60 placement. The cap 2 it is then further depressed momentarily to bring the pin 228 into engage~ ment with the plate 230, thereby to effect ener gization of the solenoid I26 and a single punching o'perationof the plate ‘E2. The pointer is‘then 65 moved into a different position on the index plate and the operation is repeated until the desired perforations have been placed on the stencil. After all desired perforations have been formed in the stencil the pedal 00 is then again momen~ 70 tarily depressed and the perforated stencil is moved out of perforating position and a new sten cil is positioned therein.
